d To all whom it ma comm Be it known that I, LYDL-i B. Keen, a citizen of the United States, and a resident of'New'York city, in the countynndstate of Ne vYor'k, have invented certain new and useful Improvements in Methods of Mann.

facturi'ng'Milk Bottles and like Construc tions, of which the following is a -full5 clear, and exactdescriptiom Among the principal objects I which; the

present 'inven'tion'hasin view are; To secure accuracy in construction 'f'and assemblage I the same.

"the parts forming the upper, section of a. paper constructed bottle, or similana'rticle;to reduce the'ainountof machinery required for 'the manufacture of the said section;to.reduce the cost of construction 'of said section; and to simplify and improve the method of constructing the said section when providing asight-gaugethereinli, U v

I Drawings]? I Figural is a side view offa bottle con-' s'tru'cted and arrange'd in" accordance with the present invention, a portion of the figure being cut away to show the-'constructionof Figure 2 is across section taken on'the line 2 2 in Figi 1. I V f Figure 3 is a'view showing theblanks from'which the upper section of the bottle 1 constructed,the blanks being superposed to show the manner in which they are produced by suitable dies, the upturned 'end'of the uppermost ply being shown. in dotted lines. Figure 4 shows one ofthe blanks having p i Figure 5 .is a similar View showingthe blanks united and in position to be molded and pressed to the shape'shown in 1. 7 V Description. I I

The'invention herein disclosed relates particularly to bottles or containers such as shown in Fig. 1 of the drawings which have frusto-con'ical top sections 10 and'cylindrical bottom sections 11; Both sections are multiply in form and preferably twoply.' The inner ply of the bottom section is preferablyslightly taller than the outer In this manner a seat is formed for the lower edges of the inner ply 12 and the superposed therein aclear View window AQCORPORATION OF DELAWARE. j

outer which idi m the walls of 'thegtop section l'O, {The plies" 12 and 13 are formed" simultaneously in the same die which cuts'ltl'ie edges" 14 and 15 of the inner ply, l 'ti 'and- 17jfor the outer ply. At the sanie'ftinie the curyed upper edgesfof 'll sioii"the \t wohplie s are severed)fromfthcisheets from' which the plies 12 and '13 are formed; 'The opening 19 isfpunched at the same operation through It will be noted by 'reference to? Fig; 3 of the drawings, that the opening 19 'is offset from the center; of thegpliesl2 and 13 T e .purhq efof h fi s 6 Pr i a, register whichfwill secure the overhang of'the two sections 'beyond h; edges of the ,otherfsectiomfas shown in; Fig. 5 of the drawings.

VVhenthe, blanks or use 12 and" '13 have been cut as shown 3, the plies are separated, and to on el or' other thereotis adhered a transparent j pait'ich 20, "preferably 'fromthe position shown in so that the ofiset-ofthe' opening lt) inthe two blanksor'plies resultsi'n providing anf ex} tension of the said plies leaving the opening -19 now disposed in the centerotthe joined phes I When the-plies 12 and13'are thus joined, and-preferably"pri orito'the setting of the adhesive "that unites? the same; they. 1- are spreadona" formor mandrel to shap'e the top section'as sho'wn inFig lof the'drawings When folded around the form or mandrel, the Overhangs between the edges 143 and l7 bf the" plies and between the edgesl'i'and '16 thereof lap one upon edges 16'an'd1 '17-""c'losely abutting to form tight arid relatively staggered joints. In thi's'position the blanks or plies12 and "13 are pressed in the shape shown in' elevation and section in Fig." 1 of the drawings. The

upper edges of the top portion 9 which form the overturned lip 21 shown in Fig. 1 of the drawings is a subsequent'operation performed after the container isifilled and after the top 22 shown in. Fig. 1 of the drawings has been disposed in position.

hen the top section 10 has been thus formed and the bottom section 11 has been injurious thereto.

- From the foregoing' it'is obvious that the cardinal points of novelty Tmay be said to reside in the method of cutting the blanks or plies 12 and 13 when superposed, as shown in Fig. 3 of the drawings, with a registering device such as the opening 19 oflset fron'ithe center of the said blanks, and subsequently reversing one of the said blanks when. adhesively securing the blanks in position where the openings 19 each register, thus providing extensions of each of the blanks overhanging the other blanks.

I Claims 1. A method of manufacturing milk bottles and like constructions.consisting in forming blanks simultaneously and of similar dimensions, said blanks having a registering opening therein offset fromthe center thereof; then reversing one of said blanks in superposed relation to the other of said blanks, the offset openingsvin said blanks being disposed in registered relation to form overhanging end extensions on each blank; and connecting said blanks together permanently.

2. A method of manufacturing milkbottles and like constructions consisting in forming blanks simultaneously andeof similar dimensions, said blanks having a registering opening therein offset from thecenter thereof; then reversing one of said blanks in superposed .relationto the other of said blanks, the offset openings in said blanks being disposed in registered relation to form overhanging end extensions on each blank; and connecting said blanks together permanently; and then bending: the connected blanks to the shape desired for said bottle;

andpermanently connecting the overhanging extensions of said blanks.

3. Amethod of manufacturing milk bottles and like constructionsconsisting in forming a plurality ofconcentric segmental blanks in the same cutting operation, and simultaneously forming within the margins of said blanks a view opening, said opening being offset from the center of said'blanks; then adhesively'securing said blanks in superposed reversed relation with said openings in register to form in each blank, an end extension overhanging the edge of the blank to which itis connected. v v

4. A method of manufacturing milk bottles and like constructions consisting in forming aplurality of concentric segmental blanks in the same cutting'operation, and simultaneously forming within the margins of said blanks a view opening, said opening being offset from thecenter of said blanks; then adhesively uniting said blanks in reversed relation, said view openings registering each with the other; and subsequently molding the connected blanks in .shape Where the overhanging extensions of said blanks lap to be adhesively connected. I

5. A method of manufacturing milk bottles and like constructions consisting in simultaneously .formingcurved" segmental blanks, said blanks being formed from paper sheets, said sheets being concentric and of different radial lengths, said lengths having within their margins a view opening formed simultaneously therein and offset from the center of the circumferential length thereof; then adhesively securing said blanks to each other in superposed reversed relation with the view openings in register, thereby fo ming atthe ends of said adhered blanks, ov rhanging single ply extensions; and then' molding said blanks to the desired shape where said extensions are lapped, one upon theother to .be adhesively connected. I

6. A method of manufacturing milk bottles and like constructions consisting in simultaneously. forming curved segmental blanks, said blanks being formed from paper sheets, said sheets being concentric and of different radial lengths, said lengths having within their margins a view opening formed simultaneously therein and offset from the center of the circumferential length thereof; then adhesively securing said blanks to each other in superposed reversed relation with the view openings in register, thereby forming at theends of said adhered blanks, overhanging single ply extensions; then insertingbetween said blanks in line with said registering openings, a transparent material; and then adhesively securing in permanent relation said blanks and transparent material.
